Grap is an expressive language for describing graphs and incorporating them into typeset documents. It is implemented as a preprocessor to Kernigan's pic language for describing languages, so any system that can use pic can use grap; both TeX and groff can use it. New features include the ability to clip lines to the frame you designate. Until this release, trying to plot lines that ran outside the frame generally resulted in a messy graph. Now lines are clipped. Also added syntax makes grap calculate tick mark locations and grid line locations, even if multiple coordinate systems are in use.
